Overall, the strong level of expression and a significant correlation between Snail1 and Snail2 expression in human breast cancer cells of the basal‐B subgroup are consistent with previous findings, and agree with the EMT‐like phenotype of basal‐B breast cancer cells (Hennessy et al., 2009; Shipitsin et al., 2007; Taube et al., 2010). The gene discussed is SNAI2; the disease is breast cancer.
